      There is a call to AccumulationExpression::factory() in a $group optimization here. SERVER-97674 will add another call in a different optimization. We should instead only call this once (maybe during parsing) and store the AccumulatorState objects for use in optimizations, rather than creating the AccumulatorState objects more than once.
